Hi，SergVivtonEnko

If you are not using MIDI to make it
You can upload split-track audio file as proof. The requirement here is that it must be at least three-track audio files, that is, it must contain at least the main melody track, rhythm track and other audio tracks that can assist in the proof
Thank you for your understanding

Hi.

Don’t rush to quarrel, but try to sort it out first.

All tracks must be loaded exclusively in WAVE format 16 bit 44100 Hz.
How I did it:

STEP 1: Open your project in DAW. For example: Cubase, Reaper, ProTools, Logic Pro, Studio One and others…

STEP 2: Save the current project to an audio track in WAVE format 16 bit 44100 Hz.

STEP 3: Additionally, save a midi project with several midi tracks (only 2 or 3 tracks are possible) or render several audio tracks separately (2 or 3 are possible). This is only to confirm the certification of your track. (And all this is written from the very beginning “mr DMmusic”)

STEP 4: Take a screenshot of the current project in your DAW. For example: Cubase, Reaper, ProTools, Logic Pro, Studio One and others… This is also only to confirm the certification of your track.

STEP 5: Create a folder named “Certification”. Place a midi project or several audio tracks (see STEP 3) and a screenshot of your current project in this folder. Archive this folder in a ZIP archive.

STEP 6: Then upload the files, the track in WAVE format and the ZIP archive to 100Audio according to the instructions.
Good luck.
